.LOCK FOR BED-LOUNGES.

SPECIFICATION forming part of Letters Patent No. 250,097, dated November 29, 1881.

Application filed October 7, 1881. (No model.) I

To all whom it may concern:

Be it known that we, LoUIs W. Orr and THOMAS MADDEN, both of Indianapolis, Marion county, Indiana, have invented an Improvement in Looks for Bed-Lounges, of which the following is a specification.

Sofa-lounges or bed-lounges as commonly made and used are so arranged that the upper part of the frame opens out from off the lower part, to which it is hinged, and rests upon the floor or upon suitable legs, thus bringing the two parts of the frame to a common level and forming the bed, both parts of the frame being stuffed on theinside, as mattresses. When closed up the top of the upper part of the folding frame, which is upholstered, forms the lounge-seat. The mattresses, being stuffed,

are likely to puff or swell out some, and it has been found necessary to use some device to hold the two parts of the folding frame together when the lounge is closed. Hooks have been employed, and latterly hooks have been combined with folding iron legs for this purpose.

Our invention we believe to be simpler and more effectual than either legs or hooks, being cheaply made, and automatic in its operation.

The drawings attached hereto will illustrate the method of constructing and using our device.

Figurelis a perspective view ot'abed-lounge opened so as to form a bed, the 1 W0 parts hinged together along the dotted line, in whichArepresents the back of the lounge, 0 the lower, and B the upper, part of the folding frame. Midway along the inner part of the lower half of the folding frame we attach a latch, D, which is fully shown in Fig. 5, and is pivoted loosely to the frame, so it can move back ward andforward. Opposite, on the upper part of the frame B, we attach the notched pieceE (more fully shown in Fig. 4) by means of a pivot, on which it moves freely. This has a slot, 0 through which passes a looped band, which serves as a handle, and which itself passes through a guide, F. (Shown in Fig. 6.)

The latch D, Fig. 5, is made heavier on the lower end, as it facilitates its play or movement on the pivot, which passes through the opening (I. d represents the latch, which engages with the curved flange 6, Fig. 4.

We preferably place our locking device in the center of the lounge-frame, because when locked at that point both parts are held firmly together, the ends as well as the center, whereas when the lounge is locked only at one end the other is likely to remain apart.

Fig. 2 represents a cross-section of a bedloungeframe opened, with our device attached; and Fig. 3 represents a cross-section of a bedlounge frame with our device attached when closed and locked.

When the lounge is closed it may readily be opened by pulling upon the handle G. This causes the end 6 to rise, the piece E turning on its pivot at e, and the curved flange e is released from the latch D, so that the lifting and unlocking are performed by one and the same movement.

Toclose the lounge the operator lifts the part B by means of the handle G, and when it passes the vertical its fall will cause the flange e to engage with the latch D,lockingthelounge securely and automatically.

What we claim, and desire to secure by Letters Patent, is

1. An automatic locking device composed of a latch, D, and a notched plate, E, having a curved flange to engage with the latch, in connection with the handle G, for unlocking and raising and lowering the folding frame of a bed-lounge.

2. The latch D and the notched plate E, having a curved flange, pivoted as shown, in combination with the guide F and handle G, for unlocking and raising, lowering, and locking the folding frame of bed-lounge.

8. In combination with the upper and lower parts of the folding frame of a bed-lounge, an automaticlocking device attached to the middle parts of the frame, constructed and arranged to operate substantially as herein shown.

4. In combination with the upper and lower parts of the folding frame of a bed-lounge, an automatic locking device wherein the handle by which the upper part is raised at the same time unlocks the two parts of the lounge.
